ジャーナル フリーIn 2003, Yoshida created the new genus Deelemanella for a single species, D. borneo collected in North Borneo. In this paper, a new species found in Papua New Guinea, D. christae n. sp., is added to this genus. The variation of the protrusion on the cephalothorax of D. borneo is shown.抄録全体を表示PDF形式でダウンロード (2988K) -

ジャーナル フリーA coelotine species, Femoracoelotes platnicki, previously known only from Taiwan, is newly recorded from Iriomote Island, southwest Japan. The genus Femoracoelotes is characterized by the presence of a palpal femoral apophysis, the absence of a median apophysis, the absence of epigynal teeth, and broad, saclike copulatory ducts connected or overlapped medially. The morphology of F. platnicki specimens collected from Taiwan, including the type specimens are reassessed. Morphological data including variation in male palpal morphology, coloration and markings are provided on the basis of fresh specimens from Iriomote Island.抄録全体を表示PDF形式でダウンロード (3662K) -

ジャーナル フリーUnderstanding the hard tick (Acari: Ixodida) fauna of the Iriomote cat (Prionailurus bengalensis iriomotensis Imaizumi 1967), an endangered species, is important for ecosystem conservation. However, there are no comprehensive reports on this topic. In this study, literature on the composition of tick species infesting Iriomote cats between 1975 and 2012 were compared. This study also reviewed on tick-borne pathogens found on Iriomote Island. Ticks Amblyomma testudinarium Koch 1844, Haemaphysalis hystricis Supino 1897, Haemaphysalis longicornis Neumann 1901, and Asiatic blue ticks (Rhipicephalus [Boophilus] microplus Canestrini 1888) were identified from Iriomote cats. Asiatic blue ticks were identified in 1975 and 1983–1985, whereas H. longicornis was identified from Iriomote cats for the first time in 2011–2012. Amblyomma testudinarium and H. hystricis were identified from Iriomote cats throughout the study period. Gene fragments of Anaplasma bovis Dumler et al. 2001, Babesia gibsoni Patton 1910, Bartonella henselae Brenner et al. 1993, Ehrlichia canis Donatien and Lestoquard 1935, Hepatozoon felis Patton 1908, and Candidatus Mycoplasma haemominutum were detected in ticks and/or animals such as domestic dogs (Canis lupus familiaris Linnaeus 1758), domestic cats (Felis catus Linnaeus 1758) and Iriomote cats on Iriomote Island. However, because the same genotypes of tick-borne pathogens were unknown or have not been detected in animal and tick species, the transmission network of tick-borne pathogens between hosts and ticks on Iriomote Island is unknown. Further studies are needed to understand the network structure of host-tick-pathogens on Iriomote Island, based on accurate identification of the pathogen genotype, and the risk of tick-borne pathogens in the Iriomote cat.抄録全体を表示PDF形式でダウンロード (751K) -

ジャーナル フリーWe measured a total of 489 adult specimens of Leiobunum japonicum using 41 populations from various parts of Japan for four characters and found that there are latitudinal clines in the length of legs (femur of the first legs: FIL) in both males and females, that conform to the converse Bergmann’s law. Measurements of a total of 318 adults from 7 sites that differ in elevation on the western and northern slopes of Mt. Daisen (Tottori Prefecture, Honshu) also revealed negative correlation of leg length (FIL) to altitude. Both the trends were not clear, especially in females, in characters that directly pertain to body itself (body length, cephalothorax length), probably due to the influence of feeding or maturation of eggs that considerably alter size of the abdomen. It was suggested that shorter period available for the growth and maturation in northern or higher populations are responsible for the latitudinal and altitudinal clines in the length of legs of the harvestmen having a univoltine life cycle with overwintering as eggs.抄録全体を表示PDF形式でダウンロード (3097K) -

ジャーナル フリーThe large orb-weaving spider genus Araneus consists of numerous species with highly variable morphologies and behaviors, and phylogenetic analyses have suggested that the genus is polyphyletic. Here, we investigated the specimens of Araneus viridiventris Yaginuma 1969, A. noegeatus (Thorell 1895), and an undescribed species. They were morphologically similar to each other but differed from the type species of Araneus. Following our molecular phylogenetic analysis using the sequencing data of five genes, we describe a new genus, Leviaraneus n. gen., which contains these species. They are small spiders with a broad, green abdomen. Moreover, we described the unknown species as a new species, Leviaraneus halabala n. sp. Additionally, Leviaraneus noegeatus n. comb. is newly recorded from Thailand, and its male is described for the first time.抄録全体を表示PDF形式でダウンロード (8047K) -

ジャーナル フリーEvarcha pulchella (Thorell 1895) is recorded for the first time from India. Hitherto, this species has not been recorded again in the last 128 years since its original description. Detailed diagnostic illustrations and photographs of specimens are provided, along with a map.抄録全体を表示PDF形式でダウンロード (16076K)

ジャーナル フリーSpiders are nearly omnipresent in tropical regions, throughout a vast range of habitats, where they act as top predators of other invertebrates. On islands, spiders may assume the role of larger mainland predators in regulating invertebrate populations. This study documents a novel predator-prey interaction between the wandering spider Ancylometes bogotensis and the land crab Gecarcinus quadratus on Coiba Island Panama Pacific. We briefly discuss the ecological implications of this predator-prey relationship and the potential influence of marine subsidies on the island’s terrestrial ecosystem.抄録全体を表示PDF形式でダウンロード (3686K)
